    Hello,
    
 
    I want to use two DDS AD9914  to generate I and Q signals up to 1400 MHz. I have read in the forum that synchronization of AD9914/9915 is only possible up to a clock frequency of 2.5 GHz. What happens if I use a greater clock rate than 2.5 Ghz, say 3.5 GHz, does it fail totally or does the synchronization just is not stable/reliable any more?
    
 
    Thanks in advance and kind regards
